Dr Barralet is a Materials Science graduate who specialised in Biomaterials during his PhD at the Interdisciplinary Research Centre in Biomedical Materials, QMW, University of London. After a postdoctoral position with Professor Aoki at Tokyo Medical and Dental University he worked at Smith and Nephew Group Research Centre, York, UK developing bone graft and casting materials. At the University of Birmingham UK he progressed research themes in tissue engineering and bone grafts in collaboration with biologist and clinical co-workers.
He specialises in Bioceramics in particular low temperature syntheses of nanocrystalline and amorphous inorganics, cold setting materials (cements) and precipitation to create new or improved materials or devices for tissue repair or delivery. Work on tissue engineering has focussed on new ways to build 3D structures using microscaffolds as building blocks for macroscale constructs. In addition calcium cross linked alginate has been evaluated as a tissue engineering scaffold. He has been awarded a Canada Research Chair in Osteoinductive Biomaterials and will work on this topic as well as extending prior work to include biomineralisation.
